Application filed July 19, 1915. Serial N0. 40,677.

To all whom may concern Be it known that I, KEN E. Roorinn, citizen of the United 'Statesfresiding at Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvements Coal-Transferring Apparatusof which the following is a specitication v This invention relates to loading and unand more particularly to an imdesigned for the from one vessel yard to a vessel proved device or apparatus purpose of transferring coal to another,- at sea, or from a ock. v An object of the invention is to provide an arrangement of cables and pulleys where by buckets may be simultaneously and opposltely moved tofacilitate loading and unloading.

A further object. of the invention is to provide a track or cable for the traveling buckets in which movement of one vessel relativelyto the other ped-ing the operation of the device. I i A. still further object of the invention is to provide an improved means for automatisally dumping the loaded or filled buckets through lowering movement thereof.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claimv which is appended hereto. and forms a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like parts throughout the several views, and in which I Figure 1 is a side elevation of my, im'

transferring device or appaof the device or apparatus as illustrated in Fig. 1.

Before proceeding with a description of to call particular atwhile i have evolved tention tothe fact that my invention with reference its use asa means for transferring coal one vessel to another at sea, the same may be, if des red, used as a means for transferring merchandise generally, sel to another, or from one place to another as occasion may demand.

may take place with-I outslaclrenmg the cable or in any way imeither from one ves a side end of Referring now to thedrawings by numerals, l designates the deck. of a vessel from which coal is taken and 2 the deck of a second vessel onto which the coal isto be transferred. Vessels, during the transfor of coal, are adapted to be placed side by side. The mast of each vessel (the masts respectively 3 and 4'), is yard arm 5 from the terminals of which pulleys 6 are hung to de- A. supporting cable or track 'Z is arranged over the pulleys 6 at one end of the respective yard arms, one end of each supporting cable thus arranged, being secured to the deck of the vessel 1 and at the opposite end to the deck of the vessel 2. AI spring 8 is preferably used as a fastening means whereby the terminals of the cables 7 are fastened to the deck of each vessel that one vesselmay move relatively to theother without causing the supporting cable to snap or break and permitting the said oableto be taut during such relative movement. Pulleys 9 are fastened to the yard arm 5 of the mast l adjacent the ends of the said arm to act asa guide means for a suitable cable 10 arranged thereover. Said cable 10 at one end 11 supported by the cable 7 while the oppothe cable 10 is secured to a traveling pulley 12 hung to depend from the other, of the said supporting cables 7. By this arrangement, one of the traveling pulleys is caused to move oppositely and at all times in a counter direction the said traveling pulleys.

An eye 13 is made a part of each travel pul ey to act as a guide means for the operating traveling pulley. The operating cable 14 associated with the travelin pulley 11 is fastened at one end to a buc et 15 and the operating cable 14- associated with the traveling pulley 12 fastened at one end to a.

bucket 316. v

Drums designated respectively 17 and 18 are mounted to operate upon-the deck of the vessel 1, each drum having the opposite end of its associated operating cable 14 fastened .t ereto.

to the other of 7 20 are fastened-to the bot tom of each bucket to facilitate movement when filled and when moved from place to $506 while unsupported by cables or the In operation, and assuming that coal is to be transferred from the deck of the vessel 1 to the deck of the vessel 2, it will be but necessary to fasten the supporting cable 7 to the yard arm terminals in the manner shown to advantage in Fig. 2. As suggested, each supporting cable carries a traveling pulley 11, from which pulley a bucket is hung to depend. Support meansfor the respective buckets will engage the operating cable 14 connected thereto. By winding the cable 14 upon the drum 17 it is evident that the said cable will be drawn taut, the bucket 15 righted and elevated sufiiciently to bring enlargement 21 of said cable in contact with the eye-13 of the traveling pulley 11. When thus contacted, continued winding of the cable 14 on said drum will cause the bucket 15 to move with the traveling pulley 11 along the supporting cable 7 until in a position directly above the deckl in which event the said bucket will be lowered and later filled with the coal to be transferred. Movement of the traveling pulley 11 in the manner stated will cause the bucket 16 said bucket having been filled with coal) to travel along the supporting cable 7 in the opposite direction from that of the bucket 15 or to a position directly over the deck of the vessel 2, at which point it may be lowered. The lowering movement of the bucket thus filled will cause the trip cable to be drawn taut and as the operating cable associated therewith is loose, the bucket will be inverted and the contents dumped in an obvious manner. During turning movement of the drum 17 in the manner stated,.

drum 18 is to be controlled by any suitable means so as to permit the bucket 16 to be held in an elevated i ion while traveling from one to the op site end of the supporting cable 7. When an operation similar to that above outlined has tal winding of the operating cable associated with the bucket 16 will cause said bucket to return to its original position above the deck of the vessel 1 and the bucket 15 to return to its original position above the deckof the vessel 2. This operation is continued until a suflicient amount or" coal has been trans .rred from one to the otherot the vessels. v

From the foregoing, taken in connection with the accompanying drawings it is evident that the vessels may move, one relatively to the other, without causing the supporting cable 7 to snap or break; that movement ofone of the supporting cables (topics of this patent may he obtained five cents each, by addr'essi place, a

- manner aforesaid.

In reduction to practice, I have found that the forin of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment,

is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of myldevice will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificingany of the advantages of my invention, as defined in the appended claim.

Having thus fully described my inven' tion, what 1 claim as new and desire to secure by Letters Patent, is

A coal transferring apparatus including masts erected upon the delivering and receiving vessels, yard arms for said the yard arm ofthe removed vessel having a pair of spaced pulleys, parallel supporting cables extended between the yard arms and supported thereby, a traveling pulley mounted on each cable, a connecting cable secured at either end to one of the traveling pulleys and passing over the yard arm pulleys whereby said traveling pulleys may move in opposite directions and in unison upon their supporting cables, an eye forming a part of each traveling pulley, a pair of drums mounted upon the delivering vei -sel, a cable for each drum passing through in ulle and said travelin' oulle is it thereby moved along the supporting in either direction as the case may be, thereby resulting in a movement of other pulley in the opposite direction, sal buckets when lowered being adapt l to be inverted, and their contents ejected by tight-- ening of the trip cable.

In testimony whereof ll a X my signature in presence of two witnesses.
